SAFETY DEVICE FOR MINES.

Specification of Letters Patent.

atent'ed Feb. 14, 1911.

Application led December 7, 1910. Serial No. 596,121.

To all w/Lom it may concern:

Be it known that I. Parnu D.\n.\nos. a subject of the King of l'lungary. residing at Oakdale. in the county of Allegheny and State of Pennsylvania. have invented certain new and use'tiul Improvements in Sat'ety Devices t'or Mines, ot which the 'following is a speeitiea'tion, re'terenee being had therein to the accompanying drawing'.

This invention relates to a sa't'ety deviee for mines, quarries, and umlergromnl workings, and the primary object oli the invention is the ]'n'ovision o't simple and etlieetive means for supplying' fresh air to a mine, particularly when explosions occur.

Another object oli' the invention is to vide a mine with a ventilating system insures perfect safety oit the miners, with stores or compartments containing aid to imprisoned miners.

attain the above objects by a deviee that will be hereinafter speeilioally described and then claimed. and re'lerenee will now be had to the drawings. wherein:

`Figure 1 is a long'itudinal sectional view ol a portion oit a mine equipped with the de viee. Fig. 2 is a horizontal seetional view ol the same looking toward the root o't the mine, and Fig. is a longitudinal sectional view ot one of the stores of the mine.

The reference numeral 1 denotes an elevator shatt .leading t'rom the surfaceot| the ground to a mine entry .2 having communicating halls or rooms 3.

4t denotes an air sha't't communieating with the entry i? adjaeent to the elevator sha'tt 1. The upper end of the ail' shaft 1 `is Closed by a hood 5 and this hood is in communication with a fan house G through the medimn ot' an opening' 7. In the fan house is located a 't'an casing' S containing ay revoluble tan E) adapted to be operated by a motor 1() or other source oitl power. the fan 9 receiving' air tln'ough an opening' 11 from the exterior o'l' the house G and delivering' the air through the opening 'l' into the shaftv il, the entry 2. and the rooms 3 thereof. The opening T can be closed by a flap door 1Q normally supported in an open position by a ledge 13 arranged at the bottom edge of the opening T. said flap door extending into the hood 5. rThe top o't' the hood 5 is provided with an opening 111 and this opening' Vis normally closed by a tlap door 15 hinged, as at 1G, to the top oitl the hood whereby the door can be swung upwardly to an open position.

prothat and first,

1T denotes a pipe arranged along the roof o'lE the entryand the 1'ooms3,and this pipe is provided with equally spaced perforated heads 1S. 'lhe pipe 1T has a tee 1S) connected to a vertical pipe 2t) extending upwardly in the air sha'lt l adjaeent to one o1 the side walls thereot. The upper end of the pipe is connected to a 'tunnel-shaped member 2l in communication with the 'lan casing S, and in the funnel-shaped member 21 is located a slide valve 92 normally held iu a` closed position by a rod S23 pivotally eonnected to the lower end Q1 of an operating lever Q5, said lever exteiuling upwardly through the floor of the fan house l() and being pivotally supported at the tloor line by barings Qt.

The mine throughout can be lighted by iucmldescent electric lamps :2T and at, suitable points or stations within the mine stores are located eomprising boxes ortanks 2S containing water 2t) and Sponges 30. the sponges being separatml lrom the 'ater 29 by a partition 3l located within the box. lasy access is had to the water Q9 and the sponges Il() through the medium oi: openiug's i12 in the top oli the box` and said openings being normally closed by hinged lids l-. lesides water and sponges other necessary `supplies adapted to render lirst aid to ent-ombed minersI can be maintained for an object that will presently appear.

lhe lan l) is operated to supply air to the miners or workmen within the entry .2 and the comumnicating rooms and should an explosion occur. the up-drat't or escape ol' the gases and lumes through the air sha'tt -l immediately closes the llap door 12. thus preventing the tan t) lrom being' injured, :md opens the llap door 15 allowing the liumcs and gases to escape. ll'hen au explosion occurs itis only necessary lor the attendant of the l'an 5l to operate the lever :la and open theslidc val\ e 22. 'l`he air within the l'an casing S will then be driven by the 't'an through the member 2l. into the pipes '2O and IT. the air being disseminated throughout the entry and the communicating rooms by the |wrlorated heads 1S. Should the `lerce ol the explosion be such as to cause a cave-in and prevent the escape o't' the miners. the entombed miners ean seek one ot' thc stores. obtain 'atei'. sponges, and such other supplies that. may be in store, the sponges when moistened and held to the nose immediately relieving' the miners 'from such gases and 'l'lunes as may have been inhaled during the interval of the explosion and the tiine ot' locating the stores.

It is thought that the operation and utility ot' the device for saving the lives of niiners will. be apparent without further description, and while in the drawings there is illustrated a preferred embodiment of the invention., it is to be understood that the structural elements thereof are susceptible to such Changes as fall within the scope of the aplliended claims.

That I Claim, is:

l. In a safety device for mines, the Coinhination with a mine having an entry, rooms, and an air shatt., ot' a hood located over said air shaft, a 'tan easing in coniniunieation with said hood, a revoluble Ytan located in said easing and adapted to supply air to sad air shaft, a tlap door adapted to control the communication between said fan Casing and said hood and extending outwardly into said hood, a l'lap door earried by the top ot said hood and adapted to be opened by an up-dralft within said shalt, a 'i air supply pipe located within said niine, a pipe establishing eonnnunieation between said air supply pipe and said tan easing, and a slide Valve adapted to Control. the supply of air it'roin said tan Casing to said air supply pipe.

ln safety device for ruines, the Coinbination with a niine haring an entry, roouis, and an air shatt, ot' a hood located over said air shaft, a lian Casing in connnunieation with said hood, a revoluble t'an located in said easing and adapted to sup ply air to said air shaft, a l'lap door adapted to Control the communication between said lian casing and said hood and extending out fardly into said hood, a flap door carried by the top of said hood and adapted to be opened by an up-dratt within said shaft, an air supply pipe located within said inine, a pipe establishing communication between said air supply pipe and said tan casing, a slide valve adapted to control the supply of air rroni said fan Casing to said air supply pipe, and perforated heads carried by said air supply pipe within said inine.

$5. ln a sa't'ety device for inines, the coinbination with a. niine having an entry, rooins, and an air shai'ft, of a hood located over said air shaft, a 'tan Casing' in Coininuuiration with said hood, a revoluble tan loi'ated in said easing and adapted to supply air to said air shaft. allap door adapted to (control the Conununieation between said tan easing and said hood and extending out ardly into said hood and adapted to he elosed by au up-dralit in said shaft, a tlap door carried by the top oLt said hood and adapted to he opei'ied by an updra'lt within said sliait't. an air supply pipe located within said ruine. a pipe connecting with said air supply pipe and extending upwardl)v in said air shaft, a tunnel-shaped Vnieniber Connecting the upper end ot said pipe with said tan Casing, a slide valve located in said member and Cont-rolling the communication between said tan easing and said air supply pipe, and perforated heads (carried by said air supply pipe within said mine.

ln testimony whereof l atl'ix iny signature in the presence of two witnesses.
